There is a portrait of Lord Delamer by a pupil of Hyacinthe Rigaud.
The 6th and eldest surviving son of the Hon. and Very Rev. Dr. Robert Booth, Nathaniel Booth succeeded in the family titles as Baron Delamer and a baronet upon the death in 1758 of his cousin George, Earl of Warrington, being a patrilineal descendant of the 1st Baron Delamer but not of the 1st Earl of Warrington; the family estates were left to the Earls of Stamford via Lady Mary Booth's marriage.
In 1743, he married Margaret, daughter of Richard Jones, of Ramsbury Manor, Wiltshire. Lord and Lady Delamer lived in London at Cavendish Square and at Brook House, Hampstead; they had two sons, both of whom died young, and a daughter, Elizabeth, who died unmarried in 1765. Lady Delamer died in 1773.
When Nathaniel Booth died in 1770 the barony of Delamer (cr. 1661) became extinct but the baronetcy was inherited by his second cousin and heir male, the Revd George Booth, Rector of Ashton-Under-Lyne, who lived at Cotterstock Hall, Northamptonshire.
